The Social Security Institute warned of an SMS and email fraud that claims a user’s account is blocked and asks recipients to click a link to activate two‑factor authentication; officials urged people to delete such messages and not click links. Separately, Maia city council warned of scams that use the Municipal Police logo to add credibility. The notices stress that Social Security does not ask for activation links by SMS or email. Residents should be cautious with unexpected messages and verify communications through official channels, especially when asked to follow a link.
